Potentiometers measure linear and rotary position – a crucial function in a wide array of modern products and applications – and High Precision Potentiometers from Hoffmann + Krippner partner Altmann GmbH can perform this function with unparalleled exactness.

Altmann offers nearly 50 years of experience in the development and production of technically advanced and high-quality products, serving customers worldwide whose need for accuracy and precision is equally unmatched, such as the nuclear industry within the U.S.

Of course, “precision” can have different meanings depending on the situation. For example, quality criteria can include resolution, repeatability, hysteresis, and reproducibility. Experts from Altmann and Hoffmann + Krippner can work with customers to understand what they really need for their specific application and to identify the perfect High Precision Potentiometer product line and model for their application.

Why use a High Precision Potentiometer from Altmann and Hoffmann + Krippner?

High precision potentiometers made to your requirements

Altmann offers an extensive product portfolio of High Precision Potentiometers that can meet a variety of needs, budgets, and applications (more information below).

However, in some cases, an existing in-stock solution may not exist, and the engineer may need to work with the sensor provider to develop a custom solution that meets the needs of that specific project. Altmann specializes in designing and building custom-made sensors.

Altmann’s and H + K’s engineering teams are skilled and experienced at working with a customer’s development group to quickly and efficiently developing custom solutions. We can also provide expertise and assistance with the integration of the sensors into the final product design.

All our standard products can be amended individually, and everything is possible from series production to single-part manufacturing. We produce your potentiometers according to your exact requirements and specifications.

Meeting high performance and safety standards

Altmann products comply with the European guidelines for product safety. Like Hoffmann + Krippner, they have set high standards for our in-house quality testing and only the perfect quality product will leave our warehouse.

We also work closely with external laboratories for third-party testing and qualifying purposes. Altmann GmbH is certified according to DIN EN ISO 9001 : 2008. The entire product range is also certified for CE and RoHs specifications.

Servo Mount

This line of Precision Angle Potentiometers is perfect for harsh industrial conditions. Noble metal winding provides the highest protection against environmental conditions, while the multiple tapper ensures safe function. Solder connections are available as an option. The potentiometers are through-rotating but can also be provided with stops upon request. Different adapter plates for attachment facilitate installation, and shafts with special lengths can be manufactured individually for single units.

Sine Cosine Output Potentiometers

Sealed Potentiometers

Note that most of our High Precision Potentiometers are available with IP protection; corresponding notes are given on the datasheets. The only product groups not IP protected (and where IP protection is also not available) are the product groups F25, SP08, LLWA, KS15, LP15 & DZVP.

Multi-Turn High Precision Potentiometers

Bushing Mount

Our multiturn High Precision Potentiometers are equipped with maintenance-free bearings and are fully customizable. They have a rotation angle area up to 3600⁰ and all types are available with 3, 5, or 10 turns. They include low-cost potentiometers that are especially well-suited for setpoint devices. IP ratings make many of these models well-suited to harsh environmental conditions. Additionally, Multi-Turn High Precision Potentiometers includes gear potentiometers (equipped with end stops and integrated with a special clip coupling to protect the gear against overloading) and motor potentiometers.

Servo Mount

Servo mount Multi-Turn are available as a special version. Please inquire for more information.

Turns Counting Dials

The ProfiAdapter accessory for precision multi-turn wirewound potentiometers can be self-installed to facilitate the use of your High Precision Multi-Turn Potentiometer. For more information, please see here and here.

Linear Motion Transducers

Linear Motion Transducers provide millimeter accuracy with robust aluminum housing and maintenance-free sliding bearing. The key advantage provided by this series is its flexibility for small quantities and various available lengths and resistances due to the wire technology used. The setup costs for the various lengths are very economical with short lead times. This wire-wound series has been proven to provide long life cycles and exceptional linearity. Additionally, even resistance tolerances of 1% are available on request.

Open Frame Linear Motion Transducer

Our open frame linear transducer is our SensoFoil® Membrane Potentiometer. Membrane potentiometers offer ultra-flat design and cost advantages that work perfectly for open frame designs and can work in situations where conventional potentiometers would falter.

Custom Potentiometer Solution Samples

Our High Precision Potentiometers can be customized to meet almost any application requirement or performance specification. Please take a look at some samples of our customized potentiometers; the listed products are all of the highest quality workmanship.
